英文摘要: The application of hyperspectral imaging in the field of cultural heritage investigation isgrowing rapidly. In this study, short wavelength infrared hyperspectral imaging (960–2500 nm) hasbeen explored as a potential non-invasive technique for in situ mapping of corrosion products onbronze sculptures. Two corrosion products, brochantite and antlerite, commonly found on the surfaces of outdoorbronze monuments, were considered. Their spatial distribution was investigated on the surface of the bronzesculpture The Man with the Key by Auguste Rodin in Oslo. The results demonstrate thathyperspectral imaging combined with image analysis algorithms can display the distribution of the two corrosionproducts in different areas (unsheltered and partially sheltered) of the sculpture.
